BF1943 integrated to BFBC2 like Vietnam?

I think having a button press to switch over to Vietnam is smart. So I hope that (IF) 1943 releases, it has a button above or below Vietnam to toggle over and start finding servers. I really hope they can get it out, I would still love to play it on PC.

Though with BF3 news revealing in March, doesn't give much of a window for it's release...
